In this work, we have performed a critical review of thermophysical properties of sulfuric acid water mixtures. The thermophysical properties analysed are: density, viscosity, refraction index, thermal expansion coefficient and mass expansion coefficient. Density of sulfuric acid-water mixture has been measured for different concentrations (10-40 wt%) in a broad temperature range (0-60 C). A new parameterization of the density has been performed using a least-square method. In this parameterization, the number of coefficients has been reduced with respect to previous works. Moreover, this new equation has been analysed in an extended region of temperatures and concentrations in ranges: {c (0-100 wt%); T (-40-100 C)}. The coefficients of thermal and mass expansion have also been calculated experimentally and a linear relation of the density has been determined in function of the variation of the temperature and concentration. In addition, viscosity and refraction index measurements have been performed at 25 C and 20 C respectively. Our results have been checked measurements of the literature (review), and show good correspondence.
